The wiring harness is car specific, depending upon how the car was shipped. You will need to get the entire forward harness, which is quite expensive as it covers a lot of the front of the car (Porsche does not break up the harness into a lot of sections). You would probably be better off looking in the junk yard or from someone that converted the car over to a race car.

You are probably also going to encounter CEL/MIL fault codes as the DME is going to be looking for communications from the PSM system and won't see it when you change the harness.

The factory harness for a non PSM 2001 car should be 996-612-951-00, around $120, but I would check that number with a dealer to be sure.

This is where I have to say I have no idea as the hydraulic units and harness for 01 and 03 have different part numbers, so the harness may not match the connector. You are also going from ABS 5.3 to ABS 5.7 as well by switching to the 2003 unit, which uses a different control unit and wheel speed sensors (by 2003, most functions were moved over to the CAN bus, so the cars had a different instrument panel that now served as the "hub" for the bus controller network).

Maybe I should look for a non abs pump from an 01?
Any differences 2001 2.7 vs 3.2 abs pump?
Thanks for good info.

Can't you go back to where you bought the pump from and ask for the harness ?
I presume it came from a car being parted out
